Number of genera

1: Fouquieria Kunth with eleven species.

Molecular analysis has complemented the work done by Henrickson (1972) regarding the intra-familial relationships, recognizing the three subgenera as monophyletic groups:-Subgenus Bronnia and Idria comprise the succulent species-Subgenus Fouquieria contains eight woody species

Status

The majority of the Fouquieriaceae species are endemic to mainland Mexico.

General notes

Also known as the Ocotillo and Candlewood family.

Trade in many species is restricted by CITES due to the small populations.

Fouquieria owes its name to P.E. Fouquier, a Parisian professor of medicine.

Both insect- (entomophilic) and bird- (ornithophilic) pollinated species are found, depending on the shape, size and colour of flowers.

Trichomes at the base of the stamens are thought to achieve two things: firstly they reduce the evaporation of nectar from the base of the flower, and secondly they draw the nectar (by means of capillary & action) up and away from the sensitive ovary, protecting it from the beaks of hummingbirds.

Waxy exudates from F. shrevei I.M.Johnst. are said to produce an agreeable aroma when burnt.

F. splendens Engelm. has a dynamic range of uses from providing a quick snack in the form of the nectariferous flowers, to use as living fences and as a boot wax.
